Description

Technical Field

[0001] This utility model relates to the field of food packaging box disinfection technology, and in particular to a food packaging box disinfection device. Background Technology

[0002] Food packaging boxes refer to various containers or packaging structures used to contain, protect, display, and transport food. They are an indispensable part of the food process from production to consumption. Using specific materials (such as paper, plastic, metal, glass, or composite materials) as a carrier, they are designed and processed to form packaging with certain shapes and functions. Their core functions are to ensure food quality and safety, extend shelf life, and facilitate storage.

[0003] Since food packaging boxes are used to store food, they need to be disinfected to prevent excessive bacteria from remaining on them. To disinfect food packaging boxes, they need to be placed inside a disinfection device, transported by a conveyor mechanism, and then disinfected by ultraviolet disinfection lamps inside the device.

[0004] When ultraviolet (UV) disinfection lamps disinfect food packaging boxes, the UV lamps can only irradiate the top and sides of the packaging boxes. Because the bottom of the food packaging boxes is in contact with the conveyor belt, the UV lamps cannot irradiate the bottom of the food packaging boxes, resulting in the bottom of the food packaging boxes not being covered by UV rays, forming a sterilization blind zone, which is prone to microbial residue. Based on the above problems, this application proposes a food packaging box disinfection device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a food packaging box sterilization device to solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A food packaging box sterilization device includes a mounting frame, a mounting shell fixedly mounted on the top of the mounting frame, an ultraviolet sterilization lamp mounted on the upper side wall of the mounting shell, an L-shaped fixing frame fixedly mounted on the rear side of the mounting frame, a flipping component for facilitating the flipping of the food packaging box on the top of the L-shaped fixing frame, a conveying component for facilitating the conveying of the food packaging box inside the mounting frame, and curtains on both the left and right sides of the mounting shell.

[0008] Preferably, the flipping assembly includes a mounting bracket and a vacuum pump fixedly mounted on the top of the L-shaped mounting frame. A servo motor is fixedly mounted on the rear side wall of the mounting bracket. An active synchronous pulley is fixedly mounted on the output end of the servo motor. A synchronous belt is meshed inside the active synchronous pulley. A driven synchronous pulley is meshed inside the synchronous belt. A hollow rotating shaft is fixedly mounted inside the driven synchronous pulley. The hollow rotating shaft is rotatably mounted inside the mounting housing. A mounting plate is fixedly mounted on the surface of the hollow rotating shaft. A flipping plate is fixedly mounted on the right side of the mounting plate. A fluororubber vacuum suction cup is fixedly mounted inside the flipping plate. A pipe is fixedly mounted on the outlet end of the fluororubber vacuum suction cup. The fluororubber vacuum suction cup is connected to the hollow rotating shaft through the pipe. A vacuum tube is fixedly mounted on the inlet end of the vacuum pump. A rotary joint is installed on the inlet end of the vacuum tube. The inlet end of the rotary joint is connected to the outlet end of the hollow rotating shaft.

[0009] Preferably, the number of fluororubber vacuum chucks is several, and the several fluororubber vacuum chucks are distributed in a linear array.

[0010] Preferably, the conveying assembly includes a geared motor fixedly installed on the front side of the mounting frame, an active roller fixedly provided at the output end of the geared motor, a fluororubber conveyor belt meshing on the surface of the active roller, a driven roller meshing inside the fluororubber conveyor belt, and a support roller overlapping inside the driven roller.

[0011] Preferably, there are several support rollers, and the support rollers, driven rollers and driving rollers are all rotatably arranged inside the mounting frame, and the fluororubber conveyor belt is made of fluororubber.

[0012] Preferably, the number of curtains is several, and the curtains are symmetrically distributed, and the curtains are made of fluororubber.

[0013] Preferably, the active synchronizing wheel and the driven synchronizing wheel are vertically aligned, and the radius of the active synchronizing wheel is smaller than the radius of the driven synchronizing wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This food packaging box disinfection device first disinfects the food packaging box with an ultraviolet disinfection lamp on the right side, and then the flipping component drives the food packaging box to flip, so that the contact surface between the food packaging box and the fluororubber conveyor belt on the right side faces upward, allowing the ultraviolet disinfection lamp on the right side to irradiate the bottom of the food packaging box. This allows the ultraviolet disinfection lamp to irradiate and disinfect different parts of the food packaging box, avoiding the situation where the bottom of the food packaging box is not covered by ultraviolet light due to contact with the fluororubber conveyor belt. This eliminates the sterilization blind spots of the food packaging box and avoids the presence of residual microorganisms on the food packaging box. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figure 1-4A food packaging box sterilization device includes a mounting frame 1, a mounting shell 2 fixedly mounted on the top of the mounting frame 1, an ultraviolet sterilization lamp 3 mounted on the upper side wall of the mounting shell 2, an L-shaped fixing bracket 22 fixedly mounted on the rear side of the mounting frame 1, a flipping component for facilitating the flipping of the food packaging box on the top of the L-shaped fixing bracket 22, a conveying component for facilitating the transport of the food packaging box inside the mounting frame 1, and curtains 21 on both the left and right sides of the mounting shell 2. The flipping component includes a mounting bracket 4 fixedly mounted on the top of the L-shaped fixing bracket 22 and a vacuum pump 13. A servo motor 5 is fixedly mounted on the rear side wall of the mounting bracket 4. A driving synchronous pulley 6 is fixedly installed at the output end. A synchronous belt 7 is meshed inside the driving synchronous pulley 6. A driven synchronous pulley 8 is meshed inside the synchronous belt 7. The driving synchronous pulley 6 and the driven synchronous pulley 8 are vertically aligned. The radius of the driving synchronous pulley 6 is smaller than the radius of the driven synchronous pulley 8. A hollow rotating shaft 9 is fixedly installed inside the driven synchronous pulley 8. The hollow rotating shaft 9 is rotatably installed inside the mounting housing 2. A mounting plate 10 is fixedly installed on the surface of the hollow rotating shaft 9. A flip plate 11 is fixedly installed on the right side of the mounting plate 10. A fluororubber vacuum suction cup 12 is fixedly installed inside the flip plate 11. There are several fluororubber vacuum suction cups 12. The disks 12 are arranged in a linear array. A pipe is fixedly installed at the outlet end of each fluororubber vacuum suction cup 12, which is connected to the hollow rotating shaft 9 via the pipe. A vacuum tube 14 is fixedly installed at the inlet end of the vacuum pump 13, and a rotary joint 15 is installed at the inlet end of the vacuum tube 14. The inlet end of the rotary joint 15 is connected to the outlet end of the hollow rotating shaft 9. The food packaging box contacts the fluororubber vacuum suction cup 12. The vacuum pump 13 extracts air from inside the fluororubber vacuum suction cup 12 through the vacuum tube 14, the hollow rotating shaft 9, and the pipe, fixing the food packaging box onto the fluororubber vacuum suction cup 12 through a pressure difference. The servo motor 5 connects to the drive synchronous pulley 6, the synchronous belt 7, and the slave... The synchronous wheel 8 drives the hollow shaft 9 to rotate, causing the mounting plate 10 to flip the fluororubber vacuum suction cup 12 to the left via the flipping plate 11. This causes the fluororubber vacuum suction cup 12 to flip the food packaging box to the left, so that the contact surface between the food packaging box and the right fluororubber conveyor belt 18 is facing upwards. The food packaging box is then disinfected by the ultraviolet disinfection lamp 3 on the left side. This avoids the situation where the bottom of the food packaging box is in contact with the fluororubber conveyor belt 18, preventing the ultraviolet disinfection lamp 3 from irradiating the bottom of the food packaging box and thus eliminating the sterilization blind spot of the food packaging box and preventing residual microorganisms on the food packaging box.

[0022] Specifically, the conveying assembly includes a geared motor 16 fixedly installed on the front side of the mounting frame 1. A drive roller 17 is fixedly installed at the output end of the geared motor 16. A fluororubber conveyor belt 18 is meshed on the surface of the drive roller 17. A driven roller 19 is meshed inside the fluororubber conveyor belt 18. A support roller 20 is overlapped inside the driven roller 19. There are several support rollers 20. The support rollers 20, driven rollers 19 and drive roller 17 are all rotatably installed inside the mounting frame 1. The fluororubber conveyor belt 18 is made of fluororubber. The output end of the geared motor 16 drives the drive roller 17 to rotate, so that the drive roller 17 drives the driven roller 19 to rotate through the fluororubber conveyor belt 18, so that the fluororubber conveyor belt 18 conveys the food packaging boxes, thereby facilitating the conveying of sterilized food packaging boxes.

[0023] Specifically, there are several curtains 21, and the curtains 21 are symmetrically distributed. The curtains 21 are made of fluororubber. The edges of the curtains 21 are tightly fitted to the housing 2 to seal the opening of the housing 2, which can prevent ultraviolet rays from leaking to the outside and protect the safety of the operators.

[0024] In use: Place the food packaging box to be sterilized on top of the fluororubber conveyor belt 18 on the right. The output end of the geared motor 16 drives the drive roller 17 to rotate, so that the drive roller 17 drives the driven roller 19 to rotate through the fluororubber conveyor belt 18. The support roller 20 supports the fluororubber conveyor belt 18, so that the fluororubber conveyor belt 18 transports the food packaging box. First, the food packaging box is sterilized by the ultraviolet disinfection lamp 3 on the right. As the fluororubber conveyor belt 18 transports the food packaging box, it comes into contact with the fluororubber vacuum suction cup 12. The vacuum pump 13 extracts the air inside the fluororubber vacuum suction cup 12 through the vacuum tube 14, the hollow rotating shaft 9 and the pipeline, so that the inside of the fluororubber vacuum suction cup 12 is in contact with the outside. A pressure difference is created in the environment, which fixes the food packaging box onto the fluororubber vacuum suction cup 12. Then, the output end of the servo motor 5 drives the active synchronous wheel 6 to rotate, which in turn drives the driven synchronous wheel 8 to rotate via the synchronous belt 7. The driven synchronous wheel 8 drives the hollow rotating shaft 9 to rotate, which in turn drives the mounting plate 10 to flip to the left. This causes the flipping plate 11 to flip the fluororubber vacuum suction cup 12 to the left, which in turn causes the food packaging box to flip to the left. This results in the food packaging box having its contact surface with the right-side fluororubber conveyor belt 18 facing upwards. The food packaging box is then transported by the left-side fluororubber conveyor belt 18 and disinfected by the left-side ultraviolet disinfection lamp 3.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
